Data Filtering for Pressure
Use the serial command AVRG to view and set the averaging time 
during which the individual pressure measurement samples are integrated 
to get an averaged reading. The averaging time is the total averaging time 
of the transmitter. 
AVRG [x]<cr>
where
X
=
1 ... 60 s (default: 1 s)
. 
Note that if the averaging time is defined to be long, the settling time at 
power-up will be long, too. 
A minimum of one-second averaging time is recommended per each 
pressure transducer. These selections are used as the factory setting 
averaging times. 
Example of setting the averaging time to 60 seconds (WMO averaging 
time for barometric pressure measurement):
